SPECIFICATION forming part of Letters Patent No. 589,516, dated September '7, 1897".

Application filed May 5, 1897. Serial No. 635,258\ (No model.)

To @ZZ whom t may concern:

Be it known that I, FREDERICK J. WEBER, of Connersville, Fayette county, Indiana, have invented certain new and useful Improvements in Car-Unloaders, of which the following is a specification.

This invention pertains to improvements in apparatus for unloading cars of grain, dsc., by pneumatic process, and the improvements will be readily understood'froin the following description, taken in connection with the accompanying drawings, in which Figure lis an elevation of my improved device; Fig. 2, a plan of the same; Fig. 3, an elevation of portions of the same, part vertical section, viewed in a direction at right anugles to the direction of View ol' Fig. l; and

Fig. 4, a longitudinal section ot' one of the flexible pipe portions. Fig. 5 is a section view o t the swivel-joint l2.

In the drawings, having general reference to Fig. l, l indicates an elevator-building orl other elevated structure into which the material is to be delivered when unloaded from the cars, it being assumed that this building or structure is provided with the apparatus usual in pneumatic transfer systems forproducing a partial vacuum; 2, a track alongside thereof; S, a second tra-ck parallel with the first one 5 4.-, a mast or other elevated structure erected between the two tracks 5 5, a car on track 2; t5, a car on track 3; 7, an inletpipe to the elevator-building leading to the top of the mast; 8, a bracket secured to the top of the mast and serving to support the outer end of pipe 7, pipe 7 having a downward turn at its outer end; i), a flexible pipejoint at the i'oot of said downward turn at the outer end of pipe 7; l0, a vertical pipe in downward prolongation of pipe 7 and suspended -from llcxible joint 9, this pipe lO :forming a pendulous pipe capable of swinging freely in any direction; 4Ill, an elbow at the foot of the vertical pipe l0; l2, a swiveljoint uniting elbow ll to pipe l0, this joint permitting of elbow ll being turned in any desired direction; lil, a flexible pipesection in prolongation ot the lower end of elbow ll; ll, a rigid pipesection in prolongation of flexible pipe 13; l5, a flexible pipe in prolongation of pipe le, and 1G a mouthpiece forming the lower terminal of the pipe system, this mouthpiece forming a curve downward from liexible pipe l5.

It will be observed that the lower portion of the pipe system is capable of being turned in any direction by reason of the presence of swivel-joint l2, and that it is capable of being swung in any direction with llexible joint 9 as a point of oscillation. lt is also obvious that the lower portion of the pipe system is capable of sidewise motion independent of the turning or swinging motion referred to, by reason of the presence of flexible sections 12S and l5. The suction end of the pipe may thus be inserted into a car on either of the tracks and the mouthpiece moved around within the car to any point, as will be understood from the dotted lines in Fig. 2. A. partial vacuum being produced at the upper end of pipe 7 and the mouthpiece 1G being introduced into the grain to be dealt with the grain enters the mouthpiece and moves up the piping and enters the elevator structure.

The preferred construction of the flexible pipe-sections 13 and 15 maybe understood `from Fig. il, though my present invention is not limited to this construction of ilexible piping, nor is that construction of flexible piping claimed herein. The flexible piping is formed of intermemberingloosely-engaging truste-conical sections 17, inclosed in a ilexible jacket 18, which jacket is held at its ends tothe main portions of the pipe by drawbands.

It is desirable that pipe-section li be telescopic, as seen at 20, so as to permit the mouthpiece to be extended farther from the mast than the swinging of the vertical pipe l0 would conveniently'permit. This provision is pref-4 erable, though not essential.

A preferred construction of the iiexible joint 9 is illustrated in section in Fig, 3, in which it is seen that the ends of the pipe intermember loosely and are inclosed in a ilexible jacket 19, secured to the pipes by drawbands, suspension-links taking the vertical strains at the joint. This special form of flexible joint is, however, neither essential to my present invention nor claimed herein.

l claim as my inventionl, In a car-unloader, the combination, substzintially as set forth, of in elevated support, an elevated pipe having a liexible joint eurl'ied by said support, a Vertiel pipe pendulous from said flexible joint, an elbow united to the base of said flexible pipe by e Swivel-joint, :ind a mouthpiece united to said elbow by pipingr having :t flexible portion.

2. In a ear-unloader, the Combination, substantially as set forth, of an elevated support, im elevated pipe having L flexible joint eerried by said support, L Vertical pipe pendulous from said flexible joint, an elbow united to the base of said flexible pipe by e swivel-joint, zi exible pipe eonneeted with the lower extremity of said elbow, i telescope pipe eonnected with the outer end of said flexible pipe7 a flexible pipe at the Outer end of said telescope pipe, :ind a, mouthpiece connected with the outer end of Said 'flexible pipe.

23. In a enr-unloader, the combination, su bstnntially as set forth, of an elevated support. an elevated pipe having a flexible joint Curried by Suid Support, L Vertical pipe pendulous from said flexible joint, an elbow united :o the base of said liexible pipe by a swivel-joint` a. curved mouthpiece, and a pipe having L iexible portion uniting the upper end of sind Curved mouthpiece with the outer end of 51nd elbow,
